l IMPROVEMENT IN MACHINE POR SHAPViNG- WOODE 4llRvAYSal The' Schedulereferred to in these Letters Patent: land making part f the same.

To all whom it may concern:

Be it knownythat we, HENRiI BLAKE, of Rindge, in the county of Cheshire,and State of New Hampshire,

and AMOS J. BLAKE, of Fitzwilliam, in said county made to the'accompanying drawings'making a part of this specification- Figure 1 ofwhich is a plan or top view of the machine, as it is arrangedfoi-euttingthe inside of the trays.

Figure 2/is a side view.

Figure 3 is 'a front view of the same.

`Figure 4 is a top view of a supplementary table or carriage for shapingthe outside ofthe trays.

Figure 5 is the end view ofthe same. y

The nature of our invention consists of an arrangement of mechanism forholding and presenting blocks or bolts of wood for the action ofvrevolving cutters, in such a manner as to insure the shaping of aconcave or convex form, such as may be desired; the said cuttersbeingmade to traverse the blocks by suitable reciprocating or vibrator-ymovements of the mechanism, guided by a model or pattern, to produce aproperlyshaped tray, which will only require the application of asmoothing-tool to'ft it for sale or use.

To enable others skilled in the artigo use our in-l vention, w. willproceed to describe its ,construction and operation.

Like letters of reference refer `to likeparts of the machine., Y

The principal frame-work of the machine is represented by the letter A,in the drawings, and Bis a revolving shaft, suspended by said. frame,and 'provided with, pulleys for Y the driving-band, from any suitablemotor, and for communicating motion to the cutters C G, which areattached to a swinging frame D, the position of which is governed by atracing-wheel, E, as it rolls upon the model or pattern F, so as toproduce a similar form from the' blocks acted upon by the cutters. l

G is a carriage, having a reciprocating motion from It is provided withsupplementary tables or carriages R' and R, which are severally adaptedfor cutting the concave and convex sides of the trays, either being usedfor its specific purpose,.as may be de sired.

l On. the supplementary table or carriage. R", used4 'edge ofthe same.

' Ast-his result could Vnot be attainedby securing the blocks and modelto the surface of a level table or carriage, it is an importantauxiliary toour machine. f

To these supplementary .tables are secured, by means of suitable dogs orclamps, the tray-blocks or bolts I I, also the model or pattern E,A andin addi- Vtion to the transverse reciprocating motion of .the

carriage G, these supplementary tables or carriages BLR", sliding on thesame, have also a movement in a ltmgitudinal direction, effected bymeans of aratchet-rack, Lrand pawl M, which are worked by cams orinclined planes, attached to frame A., so that the cutters are made totraverse the blocks I I, throughout their entire length, takinga newline of, out at each passage across the same, removing there-1 -from thesurplus material, and -reducing them to correspond with the model.

Vis a cam, for liberating the -paivl'M from the ratchet L, thusdetaching the tables B or R", which,` after suspending the motion of thecrank H, may, by hand-crank N, rack S, and pinion T, he moved quickly ineither direction, so that the cuttersrnay be made to traverse the blocksin the direction of their length, to remove. any ridges or inequalitieswhich may have been left by their passage in the other direction', themovement from the crank H being temporarily suspended.-

This arrangement for -recu'tting at 'right angles ,to

'the previous cut, is very useful in smoothing the sur-l face of thework, and facilitating the whole operrtion.

O is an adjustable plate-o1' rest, for the tracingvwheel E, which is setto forni a continuation of the model to support and guide tle cuttersproperly, asl,

they pass oil' the blocks on either side.

P is an equivalent arrangement for the convex sides of the trays.

The operation of the machine is as follows, viz:

ylhe blocks to be cut are secured lin their places on the tables R orR", together with the model which it is desiredv to duplicate, so thatthe tracing-wheel yE will be at onevend of 4the same.. The 4crank H' isthen put in'motion, and the carriage G passes' the blocks back and forthunderneath the cutters, while the pawl and rackset the upper tables R'orR" ahead in another direction at each stroke of the said lower carriageG, until the entire surface of the blocks has been presented for theaction of the cutters,

which cutters, guided by a purpendicular movement.

of the swinging frame D, from the tracingwheel and model, reproduce itsform in the blocks I I.

The cutters C Gmay be made in form of circular saws or in the form of aplane-head Orptherwise, and

the movements of the reciprocating carria e G may be produced bydifferent means than those escribed,

to effect the same object. f

-We make no claim to the use of a model or` pat'- 2. The arrangement ofthe adjustable table or rest tem for the guidance of cutters to producea similar O, in combination with the carriage R', substantially form;but

c. i in the manner herein shown and described, and for Ne do claim asour invention, and desire to sethe purpose set forth.
